IMPROVEMENT lN BLOWERS OF FRANKLlN STOVES.

Specification forming part of Letters Patent No. 7,66%. dated August 27,1850.

To aid whom it may concern:

Be it known that I, DAVID STUART, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certainImprovements in Parlor-Stoves; and I do hereby declare that thefollowing is a full, clear, and exact description of the principle orcharacter which distinguishes them from all other things before known,and of the usual manner of making, modifying, and using the same,reference being had to the accompanying drawings, of which Figure l is aperspective view; Fig. 2, a horizontal section through 00 ac,- Fig. 3, asection througl'i y y.

It is desirable that stoves for parlor use should possess the means bywhich they may be perfectly regulated, so that the fire may be adaptedto the temperature of the air in the room and be made to burn with moreor less activity at pleasure. In some stoves this objectis attained byhaving a clumsy movable blower, which, when in use, excludes all theheat from the apartment and causes the fire to burn with the utmostfiereencss, and when not required is an unsightly incumbrance, and thefire languishcs for the want of it. My aim has been to produce a stovewith a blower which may be regulated to the nicest degree in its actionon the fire, and when not in use may be withdrawn from view. This stovealso possesses the advantage of being adapted to all kinds of fuel, andmay be used as an open fireplace, a close stove, or an air-tight stove,and at the same time have an elegant and convenient form. Thecommunication with the chimney may be either direct from the upper partof the stove, or the current of hot air may be made to descend throughthe side chambers and reach the chimney by a flue under the aslrpit.This stove may be of an oblong form and ornamented according to thetaste of the manufacturer.

a is the fire-chamber, lined with fire-brick or soapstone, and having agrated bottom and front. On each side are air-chambers b b, communicating with the chimney by the flue 0 under the bottom.

(1 is a direct passage to the chimney, which is closed by a damper whenthe current is required to descend through the side chambers, b. In thefront are the folding doors 0, through which the fire is fed, and bywhich, when closed, a moderate draft is produced. These doors are glazedwith talc. Within the front plates of the stove are the sliding doors f,which meet in front and entirely close up the front of the fire, and actas a blower when the draft is admitted through the ash-pit g by openingits cover h. Vhen not in use, these doors slide back behind the frontplates of the stove, entirely out of sight and occupying but littleroom.

The doors t slide in grooves outside the stove and serve as anornamental screen for the fire, so that it may be left without risk ofcoals flying out, as well as hiding the grate and inside doors fromview. The outside doors may be omitted when not required forthesepurposes.

The sliding blowers f have great advantages over folding blowers, as,when open, they are entirely out of sight and out of the way, and theyalso admit of the outer screen-doors being closed before them, whilethey remain open themselves.

Having thus fully described my improved parlor-stove, what I claim asnew therein, and which I desire to secure by Letters Patent, is-

The inner doors or blowers, f, made to slide in grooves within the frontplates of the stove, serving, when closed, as a blower, and when not inuse being withdrawn out of the way and out of sight, substantially inthe manner and for the purposes as above described.

DAVID STUART.
